IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent N o. 135,9H2, dated February 18, 1873.

To all whom it may concern:

Be it known that I, JACOB B. HINCKLEY, of the county of Nacogdoches and State of Texas, have invented a new, useful, and Improved Oultivator; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of this specification.

My improvements relate to a cultivator, which, for convenience of operation, may be attached to the wheels or frame of any ordinary wagon or cart, or it may be operated independently of either of the above by attaching the draft animals directlyto the main or principal beam to which the plow-points are connected. The cultivator proper consists of three plows, the central one of which is rigid 1y secured to the main beam, while the two lateral plows are secured thereto by means of links pivoted in such a manner as to admit of a limited adjustability of position and distance with respect to each other, and with respect to the central plow, whereby the width of the space of land subjected to their operations may be varied, as required. One or both of the side plows may likewise be detached from the main beam and central plow, leaving the latter to be used singly, if so desired.

From the above it will appear plainly evident that my object in the construction of my device is to secure acultivator which, as such, may be made conveniently and cheaply avail? able for a variety of farm or plantation cultivating purposes.

Figure 1 is a vperspective view of my improvement as connected with two wheels, axle, and body-frame of a wagon or cart. Fig. 2 is a perspective view of the cultivator detached from the aforesaid wheels and frame,

and ready to be used independently thereof.

Similar letters of reference indicate corresponding parts. 1

ln thedrawing, A represents the wheels, B the axle, and (J the frame above mentioned. D is the central beam of the cultivator, while a is the central plow, which is rigidly secured thereto by means of the metal stirrup b and brace c. Eshows the side plows, which are secured to the short wooden beams Fby stirrup and braces similar to those used for the and sweep of the said links 0.

of the main beam D aforesaid re placed the metal straps d, to which are s ed the beams F. of the side plows by mea if the connecting-links 0. These links, b ing placed at both ends of the beams F, and connected to the straps cl by pivots f, in the manner shown, operate as parallel bars to admit of the lateral adjustability of the side plows E, and consequently of the beams F therewith connected, to any required position and distance from the central plow, limited only by the length The points of the side plows E, as will be perceived, are, by the forward and backward movement of the links or parallel bars 0, made to describe the segment of a circle, as shown by the dotted lines in the drawing, and the said side plows may be secured to any required position within the said segment of a circle by means of the sliding bars 9, pivoted at h, and provided with holesi and pins j to secure this object.

The side plows may, as is evident, be placed exactly opposite or diagonally opposite to the central plow, or one or both may be detached therefrom, as circumstances may require, and as before mentioned.

The movements of the beams F, as above indicated and described, do not in the least change the angle of position of the face of the plow therewith connected-an advantage of the greatest importance, and not yet obtained by any other cultivator with V which I- am familiar. To use my cultivator without the wheels aforesaid would necessarily require that suitable handles for its control and guidance should be attached to the central beam D. The screw-threaded bar K, passing through the rear end of the beam D, and having the wheell attached thereto, is designed to regulate the depth of the cutting of the earth by the plows, as may be required.

The lever G, moving in the upright hollow standard H, and having its lower extremity connected to the plow-beam D, is designed to subserve a similar purpose as the bar K, its

movements of elevation or depression being actuated by means of the lever m and pivoted fulcrum-bar a, the form er of which has its lower extremity connected to the said upright lever G by a pin, 0, sliding vertically within the 'QFFIc'E.

slot or groove p, as shown upon the drawing;

7 or the said lower extremity of the said lever m may be directly connected with the plowbeam d by means of the chain 4"; The handle part of the lever m may be used either forward or to the rear of the standard H, and its position of elevation or depression may be controlled, as desired, by means of notchess out within the side of the bars forming the open slot or groove 10 aforesaid.

Two cultivators, with corresponding parts and connections as above described, may, under some circumstances, be used with one pair of wheels, in which case a corresponding amount of additional animal power would, of course, be required, less the amount required to draw the wheels and frame therewith connected.

Having described my invention, what I desire to secure by Letters Patent are the following claims:

1. The beam D, ploughs a and E with straps b and braces c, beams F, straps d, pivots f, and links 0, sliding bars g, bar K, and wheel I, for the purposes specified. I

2. Lever G, standard H, lever m, fulcrumbar n, pin 0, slot or groove 19, and chain r, and notches s, in combination with the frame of a wagon or cart, for the purposes specified.
